I'm so upset. Newish samsung color laser printer won't work with mountain lion. I have a lot invested in this printer -plus have new cartridges waiting to be used. I can understand not being able to see what's happening with the printer but to not print at all. I'm pretty much out of business until the manufacturer comes up with and update. Don't know what i can do!!!! I'm getting ready for my fall start up of faith formation and as the director i don't know where to turn.
